Does anyone know of an adhesive compound that could mend a tear in a Turbo fin? I hit some rocks with my fin and tore a small hole at the bottom of the mast 'hole'. I guess that the mast pushed through the rubber material of the fin when it hit the rock. The mast did not get bent.I am worried the bottom of the mast will continue to wear on the hole increasing its size.I do have a replacement fin ordered, but would prefer to be able to repair a small hole rather than replace a fin.

I tried abike tire repair kit...but the rubber patch pulled away from the Turbo fin as if the adhesive could not adhere to it. I did roughen the fin slightly before using the adhesive. Anyone know what adhesive I should use?

As I recall, Roadrunner reckons the Mirage drive performs surprisingly well with only one fin.

It does OK, but without the other fin each stroke rolls the boat a fair amount. It's disconcerting at first, but you learn to lean into it. And that's all for today from my file of things I know, but should not.

Cyanocrylate or superglue works well, wash over with freshwater, dry and abrade the fin in the repair area, I used two types a thin and a medium to build up the layers. Once they have dried I just twisted the fin and that released the s/s mast from the glue, all still in place after a year. A small piece of non absorbent material pushed inside the split might stop the glue spreading and provide some backing if the hole is larger?
